This mod removes invulnerability frames.

In minecraft, there are 0.5 seconds of invulnerability every time you get damage, which prevents you from getting a lot of damage in monster crowds, getting shot by arrows twice in a raw, damaging players by spamming the attack...

I aimed to remove this feature in a balanced and fun way

It also revamps player damage and knockback and armor durability calculation, so auto clickers can't be exploited. (option in config) Invulnerability ticks can also be reactivated and changed in the config.
